Answer:
The basement membrane or basal lamina on which the epithelium form, made by extracellular matrix.
Explanation:
The basement membrane is the layer underlies all epithelia that is made up extracellular matrix secreted by the epithelium cells that provide structural support to the structure of epithelia.
It forms the barrier between epithelial tissues therefore once a epithelial cancer penetrate this basement membrane it will spread to all underlying tissues.
Thus, the correct answer is - The basement membrane or basal lamina on which the epithelium form, made by extracellular matrix.
The basement membrane is form of extracellular matrix that underlies all epithelia. It provides structural support to epithelia and forms a mechanical connection between epithelia and underlying connective tissue.
The basement membrane, or basal lamina, is a sheet of proteins and other substances to which epithelial cells adhere and that forms a barrier between tissues.
Epithelial cancers may have the ability to penetrate through the basement membrane and spread to underlying tissues.
Answer:
Work can be defined as transfer of energy. In physics we say that work is done on an object when you transfer energy to that object. If one object transfers (gives) energy to a second object, then the first object does work on the second object.
Explanation:
The answer you are looking for is chitin.
According to a page that I found with info on the subject,
"All arthropods have bodies divided into segments and covered with a hard EXOSKELETON. This tough casing is made of a protein called chitin, which is also found in human fingernails."

Bacterial conjugation is the correct answer of the question provided. In this type of reproduction, a tube connects between two bacterial cells. Joshua Lederberg and Edward Tatum were the ones who discovered this mechanism. This process is a type of horizontal gene transfer.
Answer:
Co-dominance
Explanation:
Considering the allele for red pigment as C<em>R</em> and that for a white pigment C<em>W</em>, a pink flower will equally express both the pigments in its phenotype and will thus have a genotype of C<em>R</em> C<em>W</em>.
Crossing CR CW × CR CW you'll get,
25% C<em>R</em> C<em>R</em> - red flowers
50% C<em>R</em> C<em>W</em> - pink flowers
25% C<em>W</em> C<em>W</em> - white flowers
